Receiving linear video streams is not restricted to television sets.
- different kinds of network connected client devices such as television sets, smart phones, tablets, phablets, set-top boxes, notebooks and computers are capable of receiving linear video streams from a video server.
- a linear video stream is broadcast and received by many client devices at the same time.
- Video on-demand enables an interactive way of watching videos.
- the end user chooses the videos to watch through a user interface.
- a single video may be selected and received or multiple videos may be selected and streamed one after the other to the client device.
- the kind of client devices can be the same as with linear streaming.
- a smart television or a set-top box capable of running software applications may be used.
- the present invention enables a client device to switch from a linear video stream to a personalized video stream such that the switch is seamless. I.e, the end user does not notice that the linear stream switches to the personalized stream, resulting in a consistent and good user experience while

- Personalized video streaming a video stream is streamed to the client device, as in linear streaming, but user interaction is possible to influence what videos are part of the video stream. Alternatively or additionally the end user may select videos as in video on-demand services, which videos will then be included in the personalized video stream.
- Personalized video streams are typically unicast from a video server to a client device.
- Personalized video streaming requires that the client device is capable of processing user input for selecting or influencing the videos in the personalized video stream. As not all client devices will be capable of such user interaction, the present invention enables receiving of a linear video stream first and only if the client device is capable of receiving personalized video streams the client device will switch to this mode of operation.
- the older set-top boxes may be capable of receiving linear video streams only, while the newer set-top boxes are also capable of user interaction.
- the end user will be able to watch a linear video stream and change channels to switch to other linear video streams, if applicable.
- a newer set-top box initially operates as an older set-top box, i.e. it starts receiving the linear video stream. If a personalized video stream is available for the channel being watched, the set-top box can switch to the personalized video stream. According to the invention this switch is made seamless, i.e. there is no abrupt switch from the linear feed to the personalized feed but instead the video in the linear feed is received until it finishes and only then the switch is made. An end user watching the video stream may not even notice that the switch has been made.
- Fig. 1 shows an exemplary embodiment of the invention wherein a seamless switch is made from a linear video stream to a personalized video stream.
- Fig. 1 shows a time-sequence diagram with data being transmitted between a video server 10 and a client device 20. Initially the linear video stream ⁇ 1001 ⁇ is received in the client device 20, denoted as 101. The video server 10 in the backend controls the switching to the
- a switching signal ⁇ 1002 ⁇ is transmitted to the client device 20, which is received as denoted 102.
- the switching signal ⁇ 1002 ⁇ contains information that is used by the client device 20 to determine 103 when the last video to be displayed from the linear video stream
- personalized video stream is received in the client device 20.
- a data pattern may be included in the linear video stream.
- the data pattern may be embedded in a video of the video stream, e.g. as a watermark within a video frame of a video channel or within an audio channel of the video.
- An embedded data pattern requires the video server to be capable of inserting the data pattern into the video and the client device to extract the data pattern from the video again, which requires relatively high
- the data pattern is transmitted as a data pattern P in between two videos of the video stream, as shown in Fig. 2.
- the data pattern is invisible to the end user while the linear video stream is being displayed.
- the boundaries may be detected through pattern recognition.
- the video server 10 analyzed the videos, e.g. at predefined intervals of 1 or 2 seconds, for specific characteristics like saturation, black levels, volume levels, or any other characteristics that can be obtained from each video, and stores these characteristics as characteristics data prior to transmission of the video in the linear video stream.
- the client device 20 also analyzes the linear video stream as it is received to generate received characteristics data.
- the pattern data is defined to be the characteristic elements within the video that are obtainable through analyzing the video.
- the characteristics data stored at the video server and the received characteristics data from the client device are then compared and matched to determine if the video has been received in the client device 20.
- the comparison and matching is typically performed at the video server, possibly in a computer connected to the video server.
- characteristics data is transmitted from the client device 20 to the video server 10.
- FIG. 2 an exemplary linear video stream 1001 is shown containing a sequence of videos ⁇ V Ll , ... , V L] , ... , V Lk , ... ⁇ .
- a data pattern P is included before video V L] , which will be the last video to be displayed on the client device. Note that after the switch the linear video stream continues to be broadcast and possibly received by other client devices.
- the linear video stream may include a switching signal in the form of a data pattern before each video in the linear video stream.
- the client device 20 may trigger the video server 10 that it can receive a personalized video stream.
- the client device 20 detects the data pattern, e.g. the data pattern P shown in Fig. 2 or the characteristic elements within the video.
- the client device 20 transmits a trigger signal ⁇ 2001 ⁇ to the video server 10, as denoted 107, which triggers the video server 10 to generate and transmit the switching signal ⁇ 1002 ⁇ to the client device 20.
- the switching signal ⁇ 1002 ⁇ may be in any format, such as a binary coded message, XML message, HTTP request or json message.
- the switching signal ⁇ 1002 ⁇ may include timing data indicative of when the last video V L] finishes. Examples of timing data are an absolute time at which to switch or a timer value which has to lapse before switching.
- Timers for acquiring the current time in the video server 10 and in the client device 20 may be out of sync, in which case the timing data as described above may result in an incorrect moment of switching to the linear video stream ⁇ 1003 ⁇ .
- the client device 20 may include a time stamp in the trigger signal ⁇ 2001 ⁇ indicative of the time of receipt of the data pattern in the client device 20, thus indicative of the start time of the last video V L] at the client device 20.
- the trigger signal ⁇ 2001 ⁇ includes the received characteristics data as obtained in the client device 20, from which the video server 10 can derive the start time of the last video V L] at the client device 20.
- the video server 10 knows the start time of the last video as transmitted to the client device 20 and compares this start time with the start time as received from the client device 10 to determine a time offset. Furthermore, any delays caused by the transmission path in between the video server 10 and client device 20 are accounted for in the time offset.
- the processing of the switching signal ⁇ 1002 ⁇ , the capability of receiving the personalized video stream ⁇ 1003 ⁇ and the detection of the data pattern P are typically implemented in a software application, computer program or app running on the client device. This software application may be started
- the software application may be started in response to an instruction thereto from the end user, denoted 109, e.g. by pressing a button on the client device 20 or on a remote control 30 controlling the client device 20.
- An important feature of personalized video streaming is the capability of receiving user input that influence which videos are included in the personalized video stream.
- User interaction may be enabled directly on the client device, e.g. through buttons, keyboard or touch screen, and/or using a remote control device.
- an exemplary remote control device 30 is used to give video related user input ⁇ 3001 ⁇ to the client device 20.
- Video related user input ⁇ 3001 ⁇ is user input that is related to the current video being received and displayed.
- Fig. 3 shows an exemplary personalized video stream 1003 containing a sequence of videos ⁇ V Pl , ... , V P] , ... , V Pk , ... ⁇ .
- video V P] is the current video being received.
- the end user may indicate whether he or she likes the current video or not.
- the user may operate a like button.
- buttons such as the like button may be physical buttons or a software implemented buttons displayed on a display.
- the user pressing a x skip to next video' button within a predefined amount of time from the beginning of the video can be indicative of not liking the video.
- the user pressing a volume button can be indicative of liking the video in case of a volume up or disliking the video in case of a volume down .
- the video related user input ⁇ 3001 ⁇ is received in the client device, as denoted 110 in Fig. 4.
- An indication ⁇ 2002 ⁇ of the video related user input e.g. in the form of a binary coded, XML, HTTP or json message, is transmitted to the video server in step 111.
- the video server 10 changes one or more videos in the personalized video stream and
- FIG. 6 and Fig. 7 show an exemplary, simplified video distribution system 40, wherein a video server 10 broadcasts a linear video stream ⁇ 1001 ⁇ to a plurality of client devices 20- 21 via a data network 40. Note that there can many client devices, possibly millions. After switching to the personalized video stream ⁇ 1003 ⁇ , client device 20 only receives the
- the video server 10 selects the videos in the personalized video stream based on the video related user input.
- the available videos at the video server are scored, which means that ranking points are assigned to the videos for each user.
- the video server 10 may be implemented as a cluster of servers and/or a plurality of servers with different functions. One or more of the servers may be implemented in a cloud environment.
- the videos in the personalized video stream are typically prepared in the video server 10 as playlists.
- the user interaction indicative of liking or disliking of videos results in the videos getting a different score.
- the selection and changing of the videos in the playlist is based on the scoring of the videos for the current user. For example: the indication of the user pressing a like button typically results in a higher scoring; an indication of the user pressing a x skip to next video' button within a predefined amount of time from the beginning of the video typically results in a lower scoring depending on the amount of time; and an indication of the user pressing a volume button typically results in a higher scoring in case of a volume up or a lower scoring in case of a volume down.
- all available videos at the video server 10 are be ranked.
- the ranking typically takes into account the scores and weight factors assigned to the videos.
- the weight factors are used to give particular videos a higher or lower ranking, e.g. based on general popularity of a video.
- the weight factors can be related to specific meta data to enable successive videos in the playlist to have commonalities based on the meta data by taking into account the weight factors.
- the scoring that is stored with each song for the current user may be multiplied or added with the weight factors, depending on the logic, to determine the ranking of each video.
- One or more of the highest ranked videos can then be selected for inclusion in the playlist.
- Separation rules may be applied to videos, e.g.
- videos can be separated by a predefined amount of time depending on the user interaction and depending on meta data fields.
- Groups of related videos may be defined. These videos may be related based on any meta data or other rules. For these related videos a specific rule may be applied re the selection of videos for the playlist. An end user may be forced to watch at least one of the related videos until the end before seeing another video. Hereto, a user interaction resulting in a negative scoring will result in the next video on the playlist being selected from the group of related videos.
- the scoring and ranking is preferably performed in real time, which means that during the transmission of the current video all the calculations and the updating of the playlist finishes, enabling the next video after the current video to be from the updated playlist .
- Fig. 5 shows an exemplary embodiment of how the video server 10 may process the scoring information and perform the ranking for updating the playlist in real time.
- a dedicated JobActor created which manages computational flow.
- Rest API creates a new JobActor and sends ASK (synchronous Akka request) JobRequest to the JobActor.
- JobActor then performs the following tasks in async and parallel way: (1) JobActor spawns MappingActor and gives it MusicVideo which is being processed now. MappingActor sends back to
- JobActor 11 ids batches which correspond to all videos relevant current by its parameters; (2) on each of the 11
- BatchRankingRequest ( ids , weight ) , JobActor updates current ranking; (3) JobActor sends SearchRequest to SearchActor to get the list of ids which will be used to select top ranking video. This list is formed from either filtered of filter is defined for player or for all music videos and removed all ids which are in player separation list; (4) when SearchResult arrived,
- JobActor stored it and checks if all updates are already made. If yes, top ranking is calculated for SearchResult; (5) after top ranked video is found, response is sent immediately to Rest API and, in background, ranking list and player is saved to the cache. Note that the whole flow of Fig. 5 can be done in
